Mexico City

The informal demonym for Mexico City residents is chilango, which was historically used pejoratively by people living outside the city.

The oldest signs of human occupation in the area of Mexico City are believed to correspond to the lower Cenolithic period (9500–7000 BC).

Mexico City primarily rests on what was Lake Texcoco, which was drained starting from the 17th century.

According to the 1921 census, 54.78% of the city's population was considered Mestizo (Indigenous mixed with European).

The 1968 Olympic Games led to the construction of large sporting facilities in Mexico City.
